Khan out to unify division

Amir Khan vowed to unify the light-welterweight division after retaining his WBA title with victory over Paulie Malignaggi.

Khan enjoyed an impressive American debut with an 11th-round stoppage of New Yorker Malignaggi, who was outclassed throughout.

And the 23-year-old former Olympic silver medallist quickly turned his thoughts to further victories, saying: "I'm making 140lb easy, I feel strong. I'm not leaving 140lb until I unify the title. Until I'm number one I'm not going to leave this division."

Speaking about the fight with Malignaggi, Khan added on ESPN: "We stuck to the game plan, we knew Paulie is a very awkward fighter, he's a great boxer, great at moving.

"We had to break him down slowly, we didn't want to run in there trying to knock him out because we would have got caught with shots.

"I knew in the last few rounds I was hurting him and all I had to do was put the pressure on him."
